[ 1/1Inequality]
    Assignment:Find the solution set of inequality lnsinx ≤lncosx .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ln sin x ≤ ln cos x         (1)

---

    From inequality(1)：
         x ≤ -30.630528 或  -30.630528 ≤ x ≤ -24.347343 或  -24.347343 ≤ x ≤ -18.064158 或  -18.064158 ≤ x ≤ -11.780972 或  -11.780972 ≤ x ≤ -5.497787 或  -5.497787 ≤ x ≤ 0.785398 或  0.785398 ≤ x ≤ 7.068583 或  7.068583 ≤ x ≤ 13.351769 或  13.351769 ≤ x ≤ 19.634954 或  19.634954 ≤ x ≤ 25.918139

    The final solution set is :
         x ≤ -30.630528 或  -30.630528 ≤ x ≤ -24.347343 或  -24.347343 ≤ x ≤ -18.064158 或  -18.064158 ≤ x ≤ -11.780972 或  -11.780972 ≤ x ≤ -5.497787 或  -5.497787 ≤ x ≤ 0.785398 或  0.785398 ≤ x ≤ 7.068583 或  7.068583 ≤ x ≤ 13.351769 或  13.351769 ≤ x ≤ 19.634954 或  19.634954 ≤ x ≤ 25.918139
